摘要
基于ANSYS模拟S45C轴的感应淬火过程,提出了感应淬火工艺的电流密度Js、电流频率f、加热时间t和一定水压下喷水冷却时间t1等参数的确定方法,在其工艺参数优化基础上预测了感应淬火的组织和硬度分布,并将模拟结果与采用Carsi组织预测修正模型的计算结果及实测组织硬度结果对比分析,结果表明预测工艺参数、组织和硬度的方法可行;同时考虑感应淬火冷却过程的换热系数h变化对计算组织和硬度分布影响。
The induction quenching process of S45C steel shaft workpiece was simulated based on ANSYS, the method of determining process parameters such as current density Js, frequency f, heating time t and cooling time t1 under certain water pressure was introduced Microstructure and hardness distribution of the steel shaft was predicted based on technology parameter optimization in the process of induction quenching, and the predicted results were compared with that by Carsi microstructure predicted correction model and actually tested results. It is found that the proposed method for predicting process parameters, microstructure and hardness distribution of the workpiece is feasible. The microstructure and hardness distribution of the quenched steel shaft was calculated and the results were certificated under cosideration of the influence of the change of heat transfer coefficient of the workpiece.
